[OSM-talk] Mapping Chicago's pedways

 I found similar issues with the cycleway network here in Telford. It had been drawn in total isolation to the rest of the map, no joins where it crossed roads or footways. I have fixed it now.

Chicago's pedway system on OSM is a bit wrong -- it's mostly
disconnected from the rest of the map (check out KeepRight for a bunch
of orange lightning bolts). This can cause problems for routers.
Apparently, Toronto's system has the same issue.


(I should also note that Chicago doesn't have hour_on and hour_off, but
that's a different issue). 


I would like to just connect the pedways to the streets that they
intersect, but that's not physically accurate; in fact, they're through
buildings (and often down stairs or elevators). Can anyone suggest a
better way to map them so that they're accurate yet routable?


I'm not local to Chicago, so it would be tough for me to go out and
directly investigate myself. But I've CC'd a colleague who does live in
Chicago and whom I might be able to pester to help out when he gets the
free time.
